9. Select proper tool for the conditions.
If the nature of the obstruction is unknown, it is good
practice to explore the obstruction and retrieve a piece
of the obstruction for inspection.
Once the nature of the obstruction is known, an ap-
propriate tool can be selected for the application. A
good rule of thumb is to start by running the smallest
available tool through the blockage to allow the backed
up water to start flowing and carry away the debris
and cuttings as the drain is cleaned. Once the drain is
open and flowing, other tools appropriate for the block-
age can be used. Generally, the largest tool used
should be no bigger than the inside diameter of the drain
minus one inch.
Proper tool selection depends on the specific circum-
stances of each job and is left to the users' judge-
ment.
A variety of other cable attachments are available and are
listed in the Optional Equipment section of this manual.
Other information on cable attachments can be found in
the RIDGID Catalog and on line at RIDGID.com.
10. Securely install tool on the end of the cable (See Figure
10). If the connection is not secure, the cutting tool
may fall off in use.
11. Position the foot switch for easy accessibility. You must
be able to hold and control the cable, control the foot
switch, and reach the FOR/O-OFF/REV switch.

12. Confirm that the FOR/O-OFF/REV switch is in the O-
OFF position.
13. Run the cord along a clear path. With dry hands
plug the drain cleaner into a properly grounded outlet.
Keep all connections dry and off the ground. If the
power cord is not long enough, use an extension
cord that:
• Is in good condition.
• Has a plug similar to that supplied on the drain
cleaner.
• Is rated for outdoor use and contains a W or W-A in
the cord designation (i.e. SOW), or complies with
H05VV-F, H05RN-F types or IEC type design
(60227 IEC 53, 60245 IEC 57).
• Has sufficient wire size (16 AWG (1.5mm
(15.2m) or less, 14 AWG (2.5mm
(15.2m – 30.5m) long). Undersized wires can over-
heat, melting the insulation or causing a fire or
other damage.
When using an extension cord, the GFCI on the
drain cleaner does not protect the extension cord. If
the outlet is not GFCI protected, it is advisable to use
a plug in type GFCI between the outlet and the ex-
tension cord to reduce the risk of shock if there is a
fault in the extension cord.
